Characteristic Description
AC, DC, Noise Reject, High Frequency Reject, Low Frequency RejectTrigger Coupling
The External Trigger path does not have a DC blocking capacitor ahead of the trigger input circuit. The
rolloff associated with AC coupling happens after the input circuit. When attempting to trigger on an AC
signal that has a DC offset, care must be used to avoid overloading the input of the External Trigger
circuit. For signals that have a large DC offset, using Channel 1 or Channel 2 (and Channel 3 or Channel
4 for the TBS1154, TBS1104, and TBS1064) with AC coupling is preferred.
Trigger Slope
Rising Edge, Falling Edge
Measurement Style A) The minimum signal levels for achieving stable frequency indication on the Trigger
Frequency Counter within 1% of correct indication.
Measurement Style B) Section 4 10.2 in IEEE Std. #1057. The m inimum signal levels required for stable
edge triggering of an acquisition when the trigger Source is DC coupled.
